A friction clutch for a motor vehicle is embodied with a centrifugal mass device, which has at least one mass-bearing compensating system. At least one component of the centrifugal mass device is equipped, to form the compensating system, with at least one chamber that holds, to a predetermined degree of fullness, a fluid medium, whose position in the chamber changes when a torsional vibration occurs. The effect resulting from this position change depends on the density and viscosity of the medium, on the one hand, and, on the other hand, on the arrangement of the chamber, which determines the vibrational behavior of the medium, the shape of the chamber, which determines the movement resistance, and its degree of fullness.

Friction clutch, in particular for motor vehicles, consisting of a driving portion as a counterpressure plate, a pressure plate oriented so that it can move axially but not rotationally with respect to the counterpressure plate, a clutch plate with clutch linings which can be fixed between the two and which is located non-rotationally on a drive shaft, whereby the clutch plate is provided if necessary with a load and/or idle damper, whereby there are also pressure elements for the clutch plate and/or the damper. On such a friction clutch, the object of the invention is to realize different, predetermined moments of friction with the identical geometry of the friction device. The invention teaches that this object can be achieved by providing as the pressure element at least one permanent magnet and/or at least one magnet system and/or at least one electrically energized magnetic circuit.

The clutch disc for a motor vehicle friction clutch comprises a hub (1) on which side discs (7, 9) are rotatably mounted, arranged axially spaced, rigidly joined together, carrying the clutch linings (17). A hub plate (19) joined with the hub (1) solid in rotation, but with rotary play, is coupled rotationally elastically by means of springs (23) with the side discs (7, 9). Mounted axially between the hub plate (19) and one of the side discs (7) is a friction ring (41) of plastic material from which there protrude lugs (39) engaging into recesses (61) of the side disc (7). The lugs (39) guide the friction ring (41) solid in rotation but axially movable on the lateral disc (7). Axially mounted between the frictional ring (41) in frictional contact with the hub plate (19) and the side disc (7) is a disc spring (43) which applies with a plurality of flexible tongues protruding from its inner circumference on the friction ring (41). The flexible tongues engage in recesses of the friction ring (41). The friction ring carries on its inner circumference radially springing clamps (63) over which, together with the disc spring (43) it can be mounted by snapping on the side disc (7) or on a constructional part connected with the side disc (7).

A motor vehicle friction clutch with automatic wear compensation has a wear compensation element, which wear compensation element can rotate around a clutch axis. The friction clutch also includes an adjustment device, which adjustment device includes a worm rotatably mounted on a carrier. The wear compensation element is a worm gear that meshes with the worm to advance the wear compensation element along the clutch axis to compensate for wear. Axial play in the direction of the clutch axis is provided between the worm gear and the worm to detect wear of the friction linings.

The disclosure relates to a drive arrangement for a flap of a motor vehicle, comprising a linear drive for producing drive movements and comprising a transmission arrangement, which is coupled to said linear drive, for transmitting the drive movements, a compensating arrangement being provided which couples two drive elements of the drive arrangement to each other in terms of drive, and, when a limit load between the two drive elements is exceeded, the compensating arrangement permitting a guided compensating movement between the two drive elements. It is proposed that the transmission arrangement provides the compensating arrangement.

Seating furniture including a base fixed in position during use, a seat unit with a seat surface, and a leg unit moveable in relation to the seat unit and having a leg support surface. The leg unit is displaceable by a movement mechanism between a storage position and a use position. The movement mechanism transfers the leg unit from the storage position into the use position, and has an intermediate support displaceable in relation to the seat unit or the base by a pivoting guide. The pivoting guide has a first pivot lever between the intermediate support and the seat unit or the base, and the movement mechanism has a sliding guide with a sliding member guided in a translatory manner on the intermediate support, and the leg unit is attached to the sliding member.

A fuel pump for delivering fuel has a housing part made from a coated material. An insert made from an electrically non-conductive material, such as for example phenolic resin, is pressed into the housing part. The insert which is produced from phenolic resin can be pressed into the housing part before a surface treatment of the housing part, since phenolic resin is not electrically conductive. As a result, the fuel pump can be produced particularly inexpensively.
